Beverly, in the county ol Essex and (lom-4 monwealth of Massuchusetts,have invented certain lm rovexnents in Eyeleting-illn chinos, of w lichthe following description, in connection with the accompanying drowings,is n specification, like reference eharacters on the drawings indicatinglike ports in the several figures.

his invention relates to machines lor setting eyelets endv erticularlyto machines having u combine punching and setting device.

Prior to this invention the o eretions incident to the setting ofeyelets leve usually' been performed either bj two seperate machines,one for punching holes inthe stock and the other for setting the eyeletsin the punched holes, or by e single machine in which separatemechanisms were provided for the punching and setting operations.Although machines have been devised prior to this invention which it wasintended should unch the hole in the stock und set the eye et at onestroke and without the necessity for moving the stock from the punchingdevice to the setting device, so far as l am aware these have not provedto be entirely satisfactory, especially in setting eyelets in thin stocksuch as palper.

A11 object of this invention t 'ierel'ore is tov provide a, machine 1nwhich the punchingr and setting devices are so'combinod that n singleprogressive movement ol' the open-itH ing mechanism both punches n holein the stock and sets the eyelct therein nccurntely` und expeditiously.l accomplish this object by providing two 'cooperating cyelet-sets, oneof which has n centrally disposed punch and the other of which has meansfor forcing the stock upon the punch. These elements are preferably soassociated that by one progressivo movelncln ofthe operatlng luech-:mism thc hole is punched, the stock is forced upon the punch so thatthe lutter projects Y beyond the stock, thel barrel of the eyelet iscarried between the unch and the stock surrounding the `uncied hole, andfinally saidlmrrcl 1s cle-nc ied by coming in to contact with thesetting device associated with the punch. lt is obvious that thediameter ol the punch ut its cutting edge must he solucwhul. less thunthel diameter of the lm rrcl of thereby injure the saune. Therelue loinsure the proper setting olthe eyrlvt n nd io utilize the punch ns uVguide for the eyeletJ it is-i1nportmlt to provide menus lor forcingthe.stock upon the punch before the eyelet is i11- serted in the punchedhole. lf this were not done, the barrel of the. eyelet would come intocontact with the stock und have n. tendency to become displaced beforeoei prop erly guided by the punch into tt. hole in the stock. The Ineenslor forcing stock upon' the punch preherubly consists ol :i yieldingsleeve surrounding the eyelet-set which carries the eyelet. Thiscyelelfset has associated. with it u centrally disposed finger to )ickup the eyelet und also to Wilp-crete with the punch. The end o this`linger is made of a size to slide snugly in .e Ji: the tubular punchund.cooperate therewith to produce u. sheurinu' notion ou the stock incutting` 'the hole. ily nie-ens oi' tin structlon the use ol' opunch-hlm# dcred unnecessdi@r und ihe unch ref nuins sha-rp much longerthun it oticrwise would. The finger is urrru'iged to )reject vinrtlmrthun the sleeve und is iiiel'ern. ily mounted so uis to yield for n`short distcuce und to stop before it has been retracted as fur as theuornmlpo'sition of thc` sleeve. The linger is thus allowed to yield ifit should. strike the rncewny while nt the same time it enuuot l):retracted lufr enough for the sleeve to come into contact with the stockbefore the p\ un.hini: operation trikes pince.

Therefore whenthc sleeve and the stripper cerne into contact with the stock lrornopposite `sides the sleeve continues its progressive movement and forcesthe stock upon the -punch while the stripper is retrau'lcd relu Sl i)llll tively to the punch. When the retrograde movement of the sleeveoccurs it is evident that the stripper will move forward rela-- tivelyto the punch and strip the eyelet and the stock in which it has been setfrom the punch.

Referring sido elevation, partly in section, of afootpower eyelctingmachine embodying the features of this invention; Fig. 2 is a verticalsectional view showing the parts in the position which they occu y justafter an eyelet has been taken from t e raceway; Fig. 3 is a verticalsectional view showingr the parts as t ey appear just after the punched;Fig. showing the stock forced u on the ign 5 is a vertical sectiona views owing the parts at the time when the eyelet is set, and Fig. 6 is aperspective view of the combined upper set and punch and the finger. Inthe drawings 2 designates a table or other support to which a fra1ne4for the machine is attached. Theupper setting device is carried by aholder 6 secured in an opening in the frame by set Screw 8. lowersetting device is carried by a plunger 10 mounted for reciprocation inthe guideway 12. The mechanism for imparting a reciprocatory motion tothe plunger comprises a lever 14 pivoted at 16 to the frame, said leverbeing connected at one end by a rod 18 to a foot-treadle or otheractuating means (not shown) and at its other end being connected to thelower end of the plunger 10 bv means of links 20 and 22 at whose pivotalpoint is pivoted a guiding link 23 ivoted at its other end on the frame.The lin 22 is ivoted t0 the lower end of the plunger an hasta laterallyrejecting arm 24 which is provided with a ro ler 25 and an engaging foce26 to produce a rocking movement of a lever 28 by rollers 30 and,y 32thereon. A raceway 34 supported on the lever 28 is shifted thereby,

Referring now to the lower settin 1 device, it will be seen that this iscarried by the plunger 10 and is reciprocated thereby. A finger 44 hasits lower end extending within a recess in the plunfer and it is allowedto yield relatively to t a spring 46 located between a The mechanism 51e plunger b means ol l s oulder 48 l eyelet-set, a finger at the centerof said latter on said linger and the bottom wall 50 of the recess."Around the u per portion of the finger is a sleeve 52 w 1cv constitutesthe lower set and which ma be held on the plunger 1() in any suita lemanner. `The upper vend of this sleeve is preferably recessed at 54 toaccommodate the eyelet. Surrounding the setting device isa sleeve 56which is normally forced upwardly by a spring 58 so that its u per endis be ond t ie end of the setting evice. This seeve is slidably securedto the settin device b a screw 60 which extends into a s ot 62 therein..The upper setting device v64 is provided with a hollow centrally dending unch 66, fthe outer surface of whic is inclined and mer d to theannular recess 67 within wliic the `nd of the eyelet is clenched. Thesetting device 64 is surrounded by a stripper 68 having an annularshoulder 7() for enga ement with an annular shoulder 72 on t e settinfdevice. The stripper is held yieldinglyiy a spring 74 located betweenthe shoulder 7() and the end of the holder 6. The spring 74 isconsiderably weaker than the s rin r 58. The u per end of the `finger 44is ltteto slide snug ywithin the punch66. The oeration of the mac e 1sas follows ce-e-'l c cperator holds the stock' a in the the actuatin rod18 whereby the plunger 10 1s raised. T le finger 44 is elevated. anden-4 ters the end eyelet in the racewa 34. Said raceway is thenretracted into t e position shown in Fig. 2 and the linger continuing torise comes into contact with the punch 66 to out a hole in the stock, asshown in Fig. 3, the punching being indicated by the refer- The plunger10 continuing to advance, the sleeve 5 comes into contact with the stockand forces it upon the punch as shown in Fig. 4, the stripper 68 at thesame time being forced upWardly. lf'pon thc vlinal u ward movement ofthe plunger the nyclet is guided over the punch, hot wenn the saine andtiie wall surroundin 111e hole punched. in the stock, and the end y ol'the nynlcl. is clenched lcontact with the upper setting device. en theplunger returns to ils initial position the sleeve 56 retires fromcontact with the stock and the strip wr 68 forces the stock and theeyelet, v. hic i has just been set, oli' of the punch 66.

While thi.- invention has been shown and' described as applied to afoot-power machine, it is evident that it may be applied to any suitableeyeleting machine.

Iaving described my invention, what I claim as new and desire .to secureby Letters Patent of the United States is 1.
